Well Water Cloudy

A few days ago my water pressure dropped severely in the house but the water was still clear. The pump was running even though there were no water on in the house and the pressure gauge was maxed out. I replaced the pressure switch but that didn't fix the pump running constantly. I noticed that the two filters that I have under the house were caked with mud around them. I then found a crack in a pipe 1 inch above the pump. So I fixed that as well and replaced the filters. My water pressure is normal and pump runs normal too, but my water is cloudy. When running it in the tub the water looks muddy. When I run it in a glass cup it looks cloudy but nothing separates. The water has always ran clear but now it doesn't. What is it and how do I fix it?
